Daft Punk won record of the year, but we're still not over that "Get Lucky" mashup with Stevie Wonder. From CNN's Todd Leopold: Back in the '70s, it was like he was winning Grammys every year, including album of the year for "Innervisions," "Fulfillingness' First Finale" AND "Songs in the Key of Life," albums released in '73, '74 and '76 respectively.

That was Metallica's first performance on the Grammy stage since the 33rd Grammy Awards in 1991. They've won eight Grammys to date. Lang Lang last performed on the 50th Grammy Awards telecast in 2008. Lang Lang is also the Grammy cultural ambassador to China. Should we call Metallica the Grammy cultural ambassadors to metal?
